What the calculator does
Tell it the space you have, or measure the cylinder that's there now, and it shows the vessel we'd make for that space and how many litres it holds, with the next size up. Or tell it the litres you need and it shows the height (or length, lying down) at every diameter we make, from short and wide to tall and slim. Compare any two sizes side by side, then send us the one you need and we'll quote it.
The ranges this tool recommends from: Unvented cylinders, Storage Calorifiers/Cylinders and Buffer vessels.
